UPCAST ® Rod
The principle of the UPCAST® process is to cast molten copper continuously through a vertical die. The lower end of the die reaches into the melt, while the metal in the upper end is solidifying inside the die and the solidified product is pulled upwards through the die by the set of pinch rolls of the withdrawal machine. At Ta Win, we produce Oxygen Free High Thermal Conductivity Copper Rod (OFHC) via direct conversion of LME Grade “A” copper cathodes. Our UPCAST® Plant casts the copper under carefully controlled conditions to prevent contamination of the pure oxygen free copper rod during the process. This method of production results in the highest grade of copper content of 99.99%. With a negligibly small content of extraneous elements, the inherent properties of copper are brought forth to an optimal degree.
The important characteristics of our high-grade copper are:
– Oxygen free
– Low Impurity Level
– Immunity to hydrogen embrittlement
– Excellent fatigue strength
– Excellent impact and flow
– Excellent workability
OFHC Copper is mainly used in plasma deposition, including the manufacture of semi-conductors and superconductor components, as well as high vacuum devices such as particle accelerators.
